Write a C++ program to calculate the factorial of a number using recursion.
#include <iostream>
using namespace std;
int factorial(int n) {
if (n == 0) {
return 1;
}
return n * factorial(n - 1);
}
int main() {
int number = 5;
int result = factorial(number);
cout << "Factorial of " << number << " is: " << result << endl;
return 0;
}
